| 摘要 |
One embodiment of the present invention provides a system that facilitates computer system monitoring. During operation, the system receives monitored signals from a computer system. The system then computes cross-correlation coefficients between the signals. Next, the system groups the signals into clusters based on the cross-correlation coefficients, wherein signals within a cluster are closely correlated. The system also monitors signals within each cluster, and checks cross correlations between signals within each cluster to identify computer system anomalies.
